MiG-29 all versions, Damper does not work properly at high speed!

Fred "Spanky" Clifton flew the Mig-29. He says there was no G-Limiter.
‘I could pull the black out of the stick and bend the airplane’ - around 28:10 in the video.

I'm talking about this! Thank you, sir! Either an authentic answer or nothing! Thank you for taking the time to find it!

I don't fly the MiG-29 anymore. The lack of a datalink makes it blind compared to 4th generation AMRAAM and AIM-54 carriers, which is not fun because its radar is too weak for effective detection. The radar is insufficient to reliably guide the R-27ER and R-27ET against fighter-sized targets, a beam or notch or split S maneuver at low altitude the radar performance inadequate to track the target. The radar is reliable only at distances where the AIM-9X can be shot in your face from 10 km away! It is only effective for the R-77 missile because it does not need to be guided to the target. And ED doesn't care about this, because the worst is the FOX 3 missile with an active radar head, so it's only effective against beginner players!

Thanks again, everyone, I learned a lot from the discussion!

Pressure and Coefficient Parameters

• cs_Kwz_g = 3.8 * 0.7: This defines a constant value likely related to the speed and pressure ratio. The comment suggests it is associated with some specific condition (Kny = 0).

• cs_q_ny_max = 17000: Maximum pressure ratio for a specific condition, probably during high-speed maneuvers.

• cs_q_ny_min = 1600: Minimum pressure ratio for the same condition.

• cs_Kny_max = 0.15: Maximum value of a coefficient related to the pressure ratio.

• cs_Kny_min = 0.031: Minimum value of the same coefficient.

• cs_q_wz_max = 26000: Maximum pressure ratio for another condition.

• cs_q_wz_min = 2000: Minimum pressure ratio for the same condition.

• cs_Kwz_max = 0.72: Maximum value of another coefficient related to the pressure ratio.

• cs_Kwz_min = 0.4: Minimum value of the same coefficient.

• cs_q_nz_max = 17000: Maximum pressure ratio for a different condition (likely the travel channel).

• cs_q_nz_min = 2000: Minimum pressure ratio for the travel channel.

• cs_Knz_max = 0.3 * 1: Maximum value of a coefficient for the travel channel.

• cs_Knz_min = 0.1 * 1: Minimum value of the same coefficient.

• cs_q_wy_max = 26000: Maximum pressure ratio for yet another condition.

• cs_q_wy_min = 2000: Minimum pressure ratio for the same condition.

• cs_Kwy_max = 1.9: Maximum value of a coefficient for this condition.

• cs_Kwy_min = 0.5: Minimum value of the same coefficient.

 

 

My two cents about those parameters:

cs_q and cs_K are gain schedule parameters in relation to dynamic pressure (q). Take Kwz as an example, it is the pitch rate feedback gain (K as gain) that is multiplied by pitch rate (Wz), and is used as a feedback for the control system.

The Warsaw Pact doctrine was not about aiming towards a sporty and fair one on one fight of Mig-29s against F-16s or whatever. It would have been about spamming the airspace with many dispensable Mig-29s in the role of point defenders against western forces. You just have to recreate that scenario in DCS and you will see the true potential of the Fulcrum!

Little fun fact on the damping system of the Fulcrum: The system creates continuously small deflections on the flight stick during flight which are very well noticeable and kind of annoying for the pilot. I really hope the full fidelity Mig-29 will have that Fulcrum specific characteristic for the force feedback joystick owners.

in DCS-yes, IRL, when Western and Eastern equipment was on similar tier it wasnt the case actully, if you look for KDR, it's really bad OVERALL for Soviet eqipment becouse of sealclubbing by US and Israel of some Arabic airforces, mind you that shortly after Yom Kippur, Israel startet getting F-15's and F-16's when Syria didnt even get Mig-23, US wars in PG were very similar, a lot of 4th gen fighters with extremaly well trained pilots against 2-3rd gen planes with little amount of new gear, also huge support fleet for Coalition in those wars and huge numerical adventage. Conficts like Iraq-Iran when both sides had similar training and similar level of eqipment actully not support one side dominance. For Vietnam Era, I dare to say that Soviet equpment proved to be better if we take a look for production cost of things like Mig-17 or 21 against F-4. Only a bit of topic

Doesn't the ingame Miggy have alpha protection? If you try to pull at high speed the system keeps limiting you.

Alpha protection sure. But the faster you are the more you will hit G limit then alpha. Especially with our 1500 kmh IAS limit

That's interesting, I didn't check how much Gs are being generated, but at high speed I think limit is 4 degrees or something.

Anyway, I don't think anyone in real life would be yanking the stick at Mach 2.

[AeriaGloria]

On the deck you hit G limit at Mach 0.8-0.85 depending on weight. 
 

if it lower alpha limit with increase of speed and thus stopped you exceeding max G, like the way MiG-19 ARU is designed, I would be very surprised but pleasantly so. As there is yhe lack of G limiter. According to CL’s charts, you should be pulling 9-12 degrees AOA on the deck at Mach 0.8-0.85 at 8-9 G
